The very first post office was established in Manito in 1851. In 1857 the post office was relocated in the Berkstressers , also known as the Egypt Station, now Manito. The first Post Master was John Rosier. Sometime during the 1890’s the Post Office relocated to the west side of the railroad tracks, north of Bernshausen Garage. This Post Office was built by Judge McComas. In the 1900’s, the office once again moved, this time south of Hibberd Service. The mail carriers in the rural areas would serve their routes by horse and closed-in rig. In November, 1952 the post office moved to new quarters. At this new location, sometime in Feb. 1965, the post office was robbed. The post office wall was ruined by the robbery, so it needed to be rebuilt. In 1970, the Manito Post office announced that A. Stetzler & Sons were given a contract to rebuild the post office. In July, 1971, the post office employees had moved into the new location on the northwest corner of Market and Washington St.

Now the Post Office is known as Willet’s Winery. It was established in 2005. Willet’s Winery opened on April 20, 2006. Chris Willet now owns the Winery.
